Cognex Corporation (NASDAQ: CGNX) today announced the new Cognex DataMan 500 image-based barcode reader, which is designed to achieve higher read rates, offer improved on-line visualization, and have higher reliability than laser scanners currently in use in logistics, postal, and retail distribution applications.

Cognex says its IDMax code reading software helps DataMan 500 achieve higher read rates by reading the 1D barcodes that laser readers cannot read, including damaged, distorted, blurred, scratched, low height, and low contrast codes. The unit can process images at up to 1,000 frames per second, reads codes in any orientation, reads 2D codes such as Data Matrix and QR, and multiple codes in the same image.

This technology allows users to see what the reader sees, either live on a monitor, or by using image archiving for later review. Eliminating moving parts offers a higher level of reliability compared to laser scanners. The auto-focus is achieved using liquid lens technology, which provides maximum operating range flexibility for even the highest speed applications. Additional benefits include auto-trigger, auto-focus, and “no read” feedback. The base unit supports standard C-Mount lenses and variable focus options.

To simplify the installation, DataMan 500 combines Ethernet communication and power delivery in one cable using Power over Ethernet (PoE). It also supports RS-232 and multiple I/O points for integration into legacy systems.

“Nothing like this has ever been seen before in an image-based barcode reader”, said Carl Gerst, Business Unit Manager for ID Products. “Our proprietary imaging and software technology allowed us to create a product that can outperform laser scanners, is easy to use, and we believe will transform the market for barcode reading.”
